Narrowly rounded lounge sofa combined with a small chair:This type of lounge sofa combined with chair can be placed in between a large open space without confining it to any of the walls. This will make the chaise lounge sofa the focus of the space. A bold color scheme for the lounge sofa and chair along with a subtle color scheme for the rest of the components of the space like the walls and floors can be a very interesting design choice to explore. Different permutations and combinations with the design principles and the color scheme of different elements can be experimented with in this type of furniture choice.
